From what I could gather from the internet about homemade tofu, information on the subject is divided into two sources: 1. By gypsum manufacturers - they say one tsp of the coagulant is sufficient to 5 gallons. 2. Home made tofu bloggers - 2 tsp per gallon is required to coagulate the milk.

So, how much gypsum is required per gallon?! Confused...


I have The Book of Tofu by William Shurtleff, and the more recent Asian Tofu by Andrea Nguyen.

Shurtleff recommends 2 tsp of gypsum for 7 1/2 to 8 cups of soy milk. Nguyen recommends 1 1/2 tsp for 8 cups of soy milk.

(These recipes are for about 1/2 gallon of soy milk. There are 16 cups in a gallon)

I can't verify with personal experience, as I use Epsom salts (magnesium sulfate) as a coagulent, but have had success with both books. So, I am sure they would both work.

  • Yup. After making yet another search, I can confirm the ruling advice is to add about 1.5/2 tsp (or 1 tbsp) of gypsum per gallon of soy milk. – rubmz Jan 2 at 7:24

  • I believe we established the accuracy of these recipes :-) – rubmz Jan 3 at 7:33
